Taking inspiration from manual-focus AI, AI-s and pre-AI Nikkor lenses, photographic.ly has created a fun new wristband for photographers, featuring f-stops from f/1.4 to f/16 using the original colour codes. (The colour coding system, which involved consistent use of specific colours on the aperture rings and DOF scales of every manual-focus Nikkor lens, was invented in order to help users quickly estimate the depth of field at any given aperture setting.) “This silicone writsband is a fantastic way to both display your love of photography and your love of photographic history,” says David Schloss, Executive Director at MacCreate/Photographic.ly. Priced at $8.49, the Nikkor-inspired f-stop bracelet ships from the US to “anywhere on the planet” for a fixed cost of $0.99. The sale of each wristband generates twenty-cents for SPCA International.
